- Blue-green stains, like the one shown up to are normally the signs of minerals the water from dripping faucets. Use a vitreous enamel cleaner like this to clean enameled tubs and avoid using scouring powders, that may scratch the surface.
- A common problem for many city dwelling residents is the issue of hard water, marked by light-gray to white discolouration. An acrylic surface cleaner such as Lumashine Acrylic Cleaner works or a vitreous enamel cleaner like the one listed above.
- Orange-brown rust marks require using a commercial bath-stain remover that contains a cleaner specifically for rust removal like Whisk Rust Stain Remover or similar brands formulated to take on rust. Some people have had success using white vinegar or lemon juice placed directly on the rust, but results may vary depending on how much rust has accumulated.
- For white tide-marks use turpentine (safe for enamel or acrylic sinks and tubs), and then rinse with using any dish washing fluid. We've also had success with Magic Sponge type products from our local 99 Cents Only Store.
